Upcoming Intel Xeons only for Apple?

There's a rumor about an Apple exclusivity on the Intel Xeon processor update. It would be used in the Mac Pro refresh and here's what's new:

6 Cores (12 threads), that's 50% more than current Xeons
12MB of cache (versus 8MB now)
32nm manufacturing (versus 45nm)
New Xeons will consume less power

As it is the case with recent Intel CPUs, the new Xeons will achieve at least performance parity on single-threaded apps, but will increase performance on multi-thread apps dramatically. On the In/Out (I/O) side, there's going to be Ethernet 10Gbps and the maximum memory amount will be 128GB. We don't expect new Mac Pros to show up before January
